Co2 Levels - Just Tested, Need Help

[IlliniGuy18]

OK so I just tested my KH and my PH and I need some help

My ph is about 7.2 and it took 11 drops to turn the water yellow in the kH test. I've looked at a couple charts but i'm not sure if I'm reading them right. Can someone help?

Check that, my pH is closer to 7.7

Alright I don't really understand...is your ph 7.2 or 7.7?
If 7.2 and kh is 11, then check this table out:

I'd say your co2 level is around 20 ppm

If its 7.7 then CO2 is 6.5, if its 7.2, then CO2 is 20, either way its low. If you've got a KH of 11d, then you need to aim for a pH of 7 which would mean you've got 30ppm CO2.

Scroll down this page for a calculator

1 drop = 1 degrees

1 drop = 1 degrees

Surley that depends on the test kit used??

I think you need to check it again

 

[hunterm8]

yes on my test kit 1 drop = 10 ppm which is not 1 deg

If its 1drop = 10ppm KH then you've got even less CO2 in the tank. Even if the pH is 7.2 that still only gives you 12ppm CO2, get more in there!
